Detailed description of the invention
Below with reference to specific embodiment, technical scheme provided by the invention is described in detail, following detailed description of the invention should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.
As shown in Figure 3, energy-saving long-acting steam generation device is dual horizontal cylindrical structure, and outer cylinder is housing 1, inner layer cylinder is heating tube 2, has cavity 3 in housing 1, and namely heating tube 2 and high-temperature flue gas pipe 4 are located in housing 1.Heating tube 2 entirety is positioned at housing 1 middle and lower part, is specifically to be positioned at housing 1 the latter half, and heating tube 2 top is generally no more than housing 1 end face cross central line.Heating tube 2 horizontally set in housing, is horizontal, heating tube 2 outer wall not with housing 1 contact internal walls, especially should have certain distance bottom heating tube 2 with bottom housing 1.Be provided with fire row in heating tube 2, fire row can make the atmosphere temperature rising in heating tube 2, and because flame combustion is directed upwardly, therefore hot-air is mainly gathered in the first half of heating tube 2.Fire row is comparatively common a kind of thermal source, its quick heating, and cost performance is high, and the present invention also can adopt other thermals source to replace fire row, plays the effect of air in intensification heating tube 2.Heating tube 2 the first half cambered surface tube wall is communicated with some high-temperature flue gas pipes 4, high-temperature flue gas pipe 4 is uniformly distributed along heating tube 2 bearing of trend (being heating tube 2 axis direction in Fig. 3), high-temperature flue gas pipe 4 is back and forth bending S-shaped (bending place also can be able to be square for circular arc shown in figure) in housing 1, also known as snakelike, as shown in Figure 4, in order to make the water homogeneous heating in housing 1, the curved shape of fume pipe should adapt with housing 1 cross sectional shape, and fume pipe both sides should suitably near housing 1 outer wall.Hot-air passes in each high-temperature flue gas pipe 4, the hot-air path that formation many is cranky in housing 1, and the flue gas that high-temperature flue gas pipe 4 gives off is discharged outside housing from housing 1 top or side.By heat exchange effect, the water in housing 1 is heated and is produced steam, is finally sent by the steam (vapor) outlet at housing 1 top.When using this device, the incrustation scale of the generation in housing 1 precipitates downwards gradually, because heating tube 2 the first half is the cambered surface projected upwards, incrustation scale cannot condense in heating tube 2 the first half, again because the cross section of high-temperature flue gas pipe 4 own is circular, itself and heating tube 2 junction are cambered surface, there is not platform or the knuckle of sediment incrustation, therefore the incrustation scale in this device more cannot deposit at junction incrustation scale, so can be deposited on housing 1 bottom surface; Because high-temperature flue gas pipe 4 and heating tube 2 junction and heating tube 2 surface all do not have incrustation scale condensation, therefore these local outer wall burn throughs can not be caused, and condensation has housing 1 bottom surface of incrustation scale can not suffer the direct heating of fume pipe or thermal source, also without burning risk of leaking, the service life of steam raising plant is significantly added thus.Obviously, heating tube 2 need meet the first half be cambered surface and high-temperature flue gas pipe 4 crossing with cambered surface place be communicated with can reach not in high-temperature flue gas pipe 4 and heating tube 2 junction, the effect of heating tube 2 surface condensation incrustation scale, the shape of heating tube 2 the latter half can convert as required, but for Simplified flowsheet and demand of controlling cost, generally heating tube 2 is designed to cylindrical shape as shown in Figure 3 or oval cylinder.
Heating tube 2 has at least one to be communicated with housing 1 is outer, sends into for extraneous air and the heating energy (as liquefied gas, electric energy).Housing 1 end face directly can offer the through hole consistent with heating tube 2 end surface shape and (can open at one, also can two all open) as heating tube air-supply energy supply hole, heating tube end face outer wall and through hole edge conjunction, via area is comparatively large, is convenient in heating tube 2, arrange fire row or carry out Maintenance and Repair operation.
In Fig. 3, the shell shape of energy-saving long-acting steam generation device is a kind of preferred exemplary, in fact, housing 1 can adopt conventional vertical and cylindrical or cuboid, the curved shape of certain fume pipe also should be changed accordingly (with reference to Fig. 1, Fig. 2), to adapt to housing 1 profile and can be advisable to the water homogeneous heating in housing 1 as far as possible.In addition, when steam generation device housing 1 is horizontal cylinder shape, its longitudinal cross-section can be positive round shape or ellipse.
Heating tube 2 size is larger, and fire row is more, then the hot-air of unit interval generation can be more, but the size of heating tube 2 meeting can affect water body capacity in housing 1, and therefore heating tube 2 diameter design is advisable at housing 1 diameter about 2/to five/3rds.
Due to housing 1 bottom deposit incrustation scale, therefore suitable distance should be had between bottom heating tube 2 and bottom housing 1, this distance is preferably set to 10 to ten/25th 1/5th of housing 1 diameter, and in 3 ~ 5 years, incrustation scale all can not touch bottom heating tube 2 like this.Even if after the use several years, heating tube 2 the latter half is touched after build-up of limescale, mainly the first half is heated owing to managing interior fire row, heating tube the latter half temperature is lower, also heating tube 2 wall burn through can not be caused, therefore adopt the steam generation device of the design very long for service life, only need interval can continue to use after cleaning incrustation scale for 1 year always, be far more than like product.
In addition, we also redesign the distribution of high-temperature flue gas pipe 4, and namely high-temperature flue gas pipe 4 is interspersed between two along heating tube 2 end face center line, and symmetrical configuration each other.Fig. 4 is the first comb schematic diagram in housing 1, Fig. 5 is the second comb schematic diagram in housing 1, first comb and heating tube 2 upper left side join, second comb and heating tube 2 upper right side join, 3rd comb and heating tube 2 upper left side join, and turn back after outer wall on the left of housing 1 extends, 4th comb and heating tube 2 upper right side join, and turn back after housing 1 outer right wall extends, by that analogy, identical with heating tube 2 delivery position every smoke evacuation tracheae, adjacent fume pipe (the present invention is adjacent fume pipe with another fume pipe nearest along heating tube axis direction) is relative along heating tube 2 end face center line with heating tube 2 delivery position.Compare the on all four structure in fume pipe direction in traditional product, alternating expression design can water body in homogeneous heating shell, makes heat exchanger effectiveness higher.
In Fig. 4, Fig. 5, heating tube end face center line and housing end face center line are point-blank, being designed with like this is beneficial to being uniformly distributed of alternating expression fume pipe, in addition, heating tube axis and housing axis being parallel in figure, be conducive to the homogeneous heating of heating inner air tube like this and evenly carry high-temperature flue gas to each high-temperature flue gas pipe, but these features should not become restriction of the present invention, in actual manufacture process, heating tube end face center line also may depart from housing end face center line, heating tube axis also may not with housing axis being parallel.
In order to verify effect of the present invention, steam generation device existing in steam generation device in the present invention and Fig. 1 is carried out contrast test by us, it is 18.7kg that the steam generation device housing of Fig. 1 structure holds the water yield, holding the water yield in steam generation device housing provided by the invention is 34.7kg, and the water yield is close to the twice of Fig. 1 device.When heating power is identical, the steam generation device of Fig. 1 structure from heating to the time producing sufficient steam be 3 minutes 40 seconds, and apparatus of the present invention from heating to the time producing sufficient steam be 3 minutes 10 seconds, speed-raising reaches 30 seconds.The flue-gas temperature that apparatus of the present invention are discharged outside housing is about 105 DEG C, close to vapor (steam) temperature.As can be seen here, apparatus of the present invention heat exchanger effectiveness is high, and the efficiency of heating surface is promoted to more than original device twice, energy-conservationly reaches more than 50%.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
